NOTE THIS LAYER IS DEPRECATED (last updated 6/7/2022). This was formerly a weekly update.

Summary The cumulative total of confirmed COVID-19 cases that have been entered into covidLINK and have been reached for contact tracing interviews as of the date of report.

Description As of 12/29/21, contact tracing data, including case counts and percentages, reflect fluctuations in case reporting resulting from a network security incident. In addition, high risk location and large gathering questions were removed from the contact tracing interview questionnaire, as the questions no longer provided actionable information on potential exposure locations due to high levels of COVID-19 community transmission. As of 1/21/22, MDH implemented a new outbound email and text-based contact tracing web survey procedure, reflected in ""Outreach within 24 hours"" metrics."

The MD COVID-19 - Contact Tracing Cases Reached and Interviewed data layer reflects the cumulative total of confirmed COVID-19 cases that have been entered into covidLINK and been reached for contact tracing interviews as of the date of report. Individuals that responded to outreach attempts and were verified as the intended call recipient are considered successfully reached. Cases are considered interviewed if they have completed the case investigation interview. Not responding to calls is the primary reason cases are not successfully reached. For cases reached, reasons for not completing an interview include scheduling conflict, hospitalization/incapacitation, and refusal to participate. Data are updated weekly on Wednesday during the 10 a.m. hour (data is reported through the previous Saturday).
